IPC: B02C7/06
Filed: 1928-01-18
Abstract: 293,651. Ericsson, J. W. Jan. 18, 1928. Crushers with vibrating jaws.-In a machine for crushing ore, stone &c consisting of two crushing plates rotatable in one and the same direction and reciprbcable relative to each other during the rotation, the whole mechanism for obtaining the crushing movement is arranged within an outer, rotatable, shell supporting both of the crushing plates, the arrangement, being such that all the components of the working stresses arising on account of the working pressure are taken up within the shell. The machine may be mounted on a vehicle and also be provided with an elevator for transferring the crushed material to a storage container. The outer cylindrical casing 1 is mounted in bearings 5, 6 and is driven by a pulley 53. Inside the cylindrical casing 1 is a hollow cylindrical member 14 mounted in bearings 49, 50 and adapted to slide axially relatively to the casing 1. A crushing jaw 11 is connected by a bayonet fitting 12 and nut 13 to an extension 10 of the casing 1; the opposing jaw 16 being connected to the sliding member 14 by a cap 17 screwed into a member 15 which is retained in position by bolts 22 engaging a block 21 which abuts against half rings 19, 20 engaged in an annular recess in the inner member 14. The member 14 is reciprocated by the eccentric movement of a pin 26 which bears at one end in a recessed member 25 axially displaced with reference to the central axis of the member 14, and at the other end in a bearing 27 which is also eccentric to the central axis of the member 1. The bearing 27 is housed in. a plate 28 having a spigot 29 eccentrically mounted in a journal 30 which is prevented from turning by rods 31 and which maintains contact with the back of the plate 28 through the medium of a spring 33. The distance between the crushing jaws is adjusted by a nut 36 which is secured in position by a lock nut. The innex member 14, on the return stroke of the crushing members, is brought back by means of springs 40 which abut at one end against the end 24 of the inner member 14 and at the other end against a plate 41 which is anchored by bolts 45 secured to a ring 47 bearing in a recess in the outer member 1. In a modification the journal 30 may be driven by a pulley to operate the machine, the arms 31 being dispensed with. The crushing jaw 11 may be secured to the part 10 by bolts; the material is fed to the machine through a conduit 60 which passes through the centre of the plate 11. The crushing plates may be provided with radial grooves of varying depth to ensure uniformity of wear, the grooves in one modification extending to the edge of the discs, in this case the inner member 14 is guided in the outer member 1 by a key and slot. Oil is placed in the casing 3 and the centrifugal action forces the oil through holes in the cylinder 14 to the bearings 49, 30.

Title: Process for the production of diffusion-resistant protective coatings
IPC: C23C4/06
Filed: 1957-01-17
Abstract: Surfaces are provided with a protective coating by forming thereon a layer or film having a spinel-like crystal structure with a lattice constant in the range 7.85 to 8.60 Angstrom units, and thereafter coating the layer or film with an epoxy resin.  The layer with the spinel structure may be formed by spraying on to the surface a molten metal or mixture of metals, e.g. aluminium, iron, manganese or alloys of aluminium with magnesium, zinc or manganese, in the presence of oxygen.  If the surface is metal, the oxide layer may be produced by treatment with an oxidising liquid e.g. nitric acid, which may contain a salt of another metal in which case a "mixed" spinel is formed.  The epoxy resin may be the condensation product of bis(4-hydroxy phenyl)-2,21-propane and epichlorhydrin and may be applied in any known manner, such as brushing, dipping or spraying. Examples are given of the production of coatings of gammaalumina by spraying aluminium through a propane-oxygen flame; of Fe2(ZnO4) by treating iron sheet with nitric acid containing zinc nitrate; of Fe2(FeO4) by treating iron sheet with nitric acid alone; of an alumina spinel by treating aluminium sheet with nitric acid; and of Al2(MgO4), Al2(ZnO4) and Al2(MnO4) by treating aluminium with nitric acid containing magnesium, zinc and manganese nitrates respectively.ALSO:Metallic surfaces are provided with a protective coating by forming thereon a layer having a spinel-like crystal structure with a lattice constant in the range 7.85 to 8.60 Angstrom units, and thereafter coating the layer with an epoxy resin.

Abstract: 743,774. Automatic lathes. B.S.A. TOOLS, Ltd. June 24, 1953 [March 24, 1952], No. 1929/52. Class 83 (3). An automatic turning machine has means for reversing the work spindle, after cutting has occurred, by a slip-drive comprising a rotor, mounted on the spindle, which is actuated at the appropriate time by fluid action to arrest the forward motion and then reverse it, stop means being provided to halt the reverse drive in a predetermined angular position of the spindle and maintain this position against the action of the slipdrive. A single spindle automatic lathe, Fig. 1, has the work spindle 3 driven in forward and reverse directions for normal functioning by two cone clutches 1 (Fig. 3, broken lines). The clutches are engaged automatically by a lever 33, Fig. 1, controlled by a cam-drum 29 on an auxiliary cam shaft 37. A collar 5 is secured to the spindle 3 so as to be circularly adjustable and is provided on its outer face with a pair of notches 9, one side of each of which is bevelled. Attached to the collar 5 is a disc 11 with blades 13 onto which a jet of air can be directed from a nozzle 15. The latter is mounted on a block 17 which also supports a pawl 19, the free end of which co-operates with the notches 9. The pawl is arranged on a pivot 21, Fig. 3, and is normally urged out of engagement with the notches 9 by a spring 22, but may be brought into engagement by a fluid-piston 25 and an abutment 23 on the pawl. The piston 25 projects from the block 17 to which air pressure is led from a line 50 and a valve block 49 at another part of the machine adjacent the auxiliary camshaft. A lever 34 pivoted at 31 below the pawl 19 is operated by a projection 27 depending therefrom and operates to close a valve 30 to shut off the air supply to the nozzle 15 when this is no longer required. Operation. A cam on the drum 29 operates a lever 43 and valve 47 which opens the line 50 to air pressure, the clutches 1 having been disengaged. Air pressure is supplied to the nozzle 15 and piston 25 so that the pawl 19 engages the notches 9, the pawl slipping past the notches during forward rotation. Meanwhile the air pressure on the blades 13 slows up the spindle 3 and finally reverses it, the pawl 19 engaging the first slot encountered to stop the spindle in a predetermined position for a milling or other operation. Air is cut off from the nozzle 15 by movement of the lever 34 during this time. When the valve 47 is closed by the auxiliary cam-shaft the pawl 19 is released and the spindle rendered free for further rotary operations on the work through the normal driving clutches.
